The bearings are cheap for the stub axles if they are tapered. The shims in between the bearings will probably match the new bearings without a problem. If it were me, I would order the stub axle seal, pull the stub axles apart, replace the seals and the bearings.

You do need a bearing press of some type. I have one from Harbor Freight I use. The tolerance is 0 - .003" end play.
